Detailed ways

The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and/or" in the specification and claims represents at least one of the connected objects, and the character "/" generally indicates that the objects associated with each other are in an "or" relationship.

The data transmission method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

In the prior art, the server maps each port of the terminal to the public network and establishes a session with the terminal to achieve data transmission. However, the terminal has multiple ports, and the server needs to map all the ports of the terminal used for the session to the public network, occupying multiple public network port resources. In this case, since the terminal that has a session with the server is limited by the public network port resources, and each terminal needs to occupy multiple public network port resources to establish a session with the server, the server can only have a session connection with a limited number of terminals.

In order to solve the above-mentioned technical problems, the embodiment of the present application provides a data transmission method. Please refer to Figure 1, which is a flow chart of the data transmission method provided by the embodiment of the present application. The data transmission method provided by the embodiment of the present application includes the following steps:

S101, a first server cluster receives N first data packets sent by a second server cluster; each first data packet includes data to be transmitted and address information of a target terminal, and N is a positive integer greater than 1.

The first server cluster is a routing server cluster, which is used to send the first data packet directly to the target server after receiving N first data packets sent by the target terminal. In the same session, the source address of the first data packet received by the target server is required to remain unchanged. Therefore, in the same session, the first data packet of the terminal is sent from the same first server in the first server cluster to the target server. In the same session, the data packet includes the address information of the target terminal and the data to be transmitted, and the types of the N first data packets are different, and N is a positive integer greater than 1.

The address information of the target terminal is Internet Protocol (IP) information.

The N first data packets are data packets sent from the ports of the target terminal, and the types of first data packets sent from the ports of different target terminals are different. For example, the first data packet includes video data and audio data of a video conference. It can be understood that the N first data packets are all data packets sent by the target terminal, so the address information of the data packets is the same. The first server determines that the data packet comes from a target terminal through the address information, and performs the same sending processing on the data packets with the same address information. Please refer to the subsequent embodiments.

S102, the first server cluster sends the N first data packets to the target port in the target server according to a preset first mapping relationship; the first mapping relationship is used to represent the mapping relationship between the address information of the target terminal and the address information of the target port.

The target server is a conference server, which is used to process the first data packet related to the video conference; the target port is a media port of the conference server, which is used to receive or send the first data packet related to the video conference. The first mapping relationship includes the mapping relationship between the address information of the target terminal and the target port of the target server, and the target port is a port of the target server.

In this step, after receiving the first data packet of the target terminal, the first server cluster sends the data packet to the target server according to the first mapping relationship, completing the data transmission process of sending the data packets of multiple ports of the target terminal to the target port of the target server. Specifically, after receiving the first data packet with the same address information, the first server cluster queries the preset mapping relationship to determine the first mapping relationship; determines the target port of the target server according to the first mapping relationship, and then sends the received first data packet to the target port of the target server.

It should be understood that in a video conference, one or more terminals establish a session with the target server, and the first server cluster is preset with a mapping relationship corresponding to the address information of multiple terminals. For example, the first terminal and the second terminal need to establish a session with the target server. At this time, the first server cluster receives the first data packet of the first terminal and the first data packet of the second terminal, the first data packet of the first terminal includes the address information of the first terminal, and the first data packet of the second terminal includes the address information of the second terminal; then confirms the target server according to the address information of the first terminal, and confirms the target server according to the address information of the second terminal; sends the data packet of the first terminal and the data packet of the second terminal to the target port of the target server, and establishes a session between the first terminal and the target server, and a session between the second terminal and the target server.

Optionally, the first server cluster sends the N first data packets to a target port in a target server according to a preset first mapping relationship, including:

The first server cluster performs a hash operation on the address information of the target terminal included in the N first data packets to obtain a first hash value;

When the first hash value is the same as the second hash value, the first server cluster Mapping relationship, sending the N first data packets to the target port in the target server;

The second hash value is determined based on a hash operation on the address information of the target terminal included in the second data packet, and the second data packet is a data packet initially sent by the second server cluster to the first server cluster.

In this embodiment, the second server cluster sends the second data packet of the target terminal to the first server cluster, so that the first server cluster determines the second hash value after receiving the second data packet; after receiving the first data packet, the first server cluster determines the first hash value according to the address information of the first data packet, compares the first hash value with the second hash value, and determines whether the first data packet is sent by the target terminal. When the first hash value is the same as the second hash value, N first data packets are sent to the target server according to the first mapping relationship. In this way, the second data packet is sent from the first server cluster to the second server cluster, so that in the same session, the first data packet of the target terminal received by the first server cluster is always sent by the same second server in the second server cluster, so that the streaming data is transmitted through the same intermediate node, ensuring that the source address received by the target server does not change during a complete session.

It should be understood that the second server cluster is a load balancing (SLB) server cluster, which is used to distribute the data packets sent by the target terminal to multiple load servers for execution after receiving the data packets sent by the target terminal. To ensure that the source address received by the target server does not change in the same session, the second server cluster sends the data packets of the target terminal to the first server cluster from the same load server.

For example, please refer to FIG. 2, which is a schematic diagram of a terminal sending a data packet to a target server provided in an embodiment of the present application. In FIG. 2, after receiving the data packet sent by the target terminal 201, the second server cluster 202 distributes the data packet according to the historical sending information and distributes the data packet to the load server L1. The load server L1 sends the data packet to the routing server R1 of the first server cluster 203 according to the historical sending information, and the routing server R1 sends the data packet of the target terminal 201 to the server S1 in the target server 204.

Optionally, the first server cluster includes M first servers, and the first server cluster establishes an association relationship between the M first servers based on a hash ring, the hash ring is determined based on address information corresponding to the M first servers, and M is a positive integer greater than 1;

The hash ring is used to determine a first target server, where the first target server is a server in the first server cluster, and the first target server is used to receive N first data packets sent by the second server cluster.

Wherein, the hash ring is a virtual ring, and the second server cluster determines the first target server based on the hash ring. Exemplarily, as shown in Figure 3, there are M nodes on the hash ring, and each node corresponds to a first server. Wherein, the range of hash values between each node is represented. For example, there are 3 nodes on the hash ring, node R1, node R2 and node R3, the range of hash values between node R1 and node R2 is [0,100], the range of hash values between node R2 and node R3 is [100,200], and the range of hash values between node R3 and node R1 is [200,300]. The first target server is determined by the hash value determined by the hash ring and the second server cluster, as detailed in the subsequent embodiments.

In this embodiment, the first target server is determined by the hash ring and the hash value determined by the second server cluster, and then the first target server continuously receives N first data packets sent by the second server cluster, thereby achieving fixation of the intermediate transmission stage.

Optionally, the first server cluster is based on a hash ring and P virtual servers between the N first servers. A virtual server is set between the first servers that are adjacent to each other on the hash ring, and the address information of the virtual server is the same as the address information of the corresponding first server, and P is a positive integer greater than 1;

The hash ring and the P virtual servers are used to determine the first target server.

Among them, M first servers establish an association relationship based on a hash ring. When the second server cluster determines the first target server, there is a situation where more access is concentrated on a certain node. Therefore, a virtual server is introduced based on this to reduce the access volume of a single node.

Exemplarily, as shown in Figure 4, three first servers establish an association relationship based on a hash ring, and two virtual servers are added between each first server. The address information of the virtual server is the same as the address information of the first server, so that after determining the virtual server, the second server cluster sends N first data packets to the first server.

For example, the hash value range between node R1-1 and node R2-1 is [0,33], the hash value range between node R2-1 and node R3-1 is [34,67], and the hash value range between node R3-1 and node R1-2 is [68,100]. Among them, the range between node R1-1 and node R1-2 is still [0,100], which corresponds to the range between node R1-1 and node R2-1, node R2-1 and node R3-1, and node R3-1 and node R1-2. The address information corresponding to node R1-1, node R2-1, and node R3-1 are all one address information, which is the address information of the first server R1, wherein node R1-1 and node R2-1 are virtual server nodes. When the determined hash ring positions are node R1-1, node R2-1, and node R3-1, the first target server is determined to be the first server R1, as shown in Figure 5.

In this embodiment, by adding a virtual server to the hash ring, the access volume of a single node is reduced, thereby achieving load balancing of the first server cluster.

Optionally, before the first server cluster receives the N first data packets sent by the second server cluster, the method further includes:

The first server cluster receives a second data packet sent by the second server cluster and a third data packet sent by the target server; the second data packet is a data packet sent by the second server cluster to the first server cluster for the first time, and the second data packet includes address information of the target terminal, and the third data packet is a data packet sent by the target server to the first server cluster for the first time, and the third data packet includes address information of the target port;

The first server cluster establishes the first mapping relationship based on the address information of the target terminal and the address information of the target port.

In this embodiment, the first mapping relationship includes the mapping relationship between the address information of the target terminal and the target server, and in the data transmission of the video conference, the target terminal does not always transmit data with the target server, and different terminals have mapping relationships with different servers in different sessions. In this embodiment, the first mapping relationship is established before the first server cluster receives the N first data packets sent by the target terminal, so that the target terminal and the target server establish a session.

The second data packet is a data packet sent by the target terminal to the target port of the target server, and the third data packet is a data packet sent by the target server to the address information of the target terminal. Before the target terminal sends the second data packet to the target port of the target server, the target terminal needs to receive the target port information of the target server. Similarly, before the target server sends the third data packet to the address information of the target terminal, the target server needs to receive the target port information of the target terminal. The process is as follows:

Please refer to FIG6 , which is a schematic diagram of establishing a first mapping relationship provided by an embodiment of the present application. Before the target terminal 201 and the target server 204 establish a session, they need to register through the messenger server 301 in FIG6 , the target terminal 201 sends the address information to the messenger server 301, and the target server 204 sends the target port information to the messenger server 301, and the messenger server 301 stores the address information and the target port information. When the target terminal 201 and the target server 204 establish a session, the messenger server 301 sends the target port information of the target server 204 to the target terminal 201, and sends the address information of the target terminal 201 to the target server 204.

Furthermore, the first server cluster 203 receives the address information of the second data packet of the target terminal 201 and the address information of the third data packet of the target server 204, and establishes a first mapping relationship.

Optionally, the N data packets include:

Audio data packets of the first protocol, audio data packets of the second protocol, video data packets of the first protocol, video data packets of the second protocol.

It should be understood that the data transmission of the video conference includes audio data and video data, which are transmitted through the first protocol and the second protocol respectively. Among them, the first protocol is the Real-Time Transport Protocol (RTP), and the second protocol is the Real-Time Transport Control Protocol (RTCP). In the target terminal, different interfaces are used to send data packets of different protocols; in the target server, one media interface is used to receive all data packets to realize port multiplexing, thereby reducing the occupation of public network port resources by the session and increasing the number of terminals that can be connected to the target server.

Exemplarily, the third data packet includes a message sent by the target terminal 201 to the target server 204 as shown in Table 1:

Table I

Among them, the target terminal 201 sends the third data packet to the target server 204. The specific process is that the target terminal 201 sends the third data packet to the second server cluster 202, and then the second server cluster 202 sends the third data packet to the first server cluster 203, and finally the first server cluster 203 sends the third data packet to the target server 204.

It should be understood that the process of the target terminal 201 sending the third data packet to the second server cluster 202 is an external network transmission process, while the process of the first server cluster 203 sending the third data packet to the target server 204 is an internal network transmission process. Among them, when the target terminal 201 sends the third data packet to the second server cluster 202, it sends the third data packet to the public network address of the target port of the target server, that is, Port-A in Table 1; after receiving the third data packet, the second server cluster 202 After that, it is sent to the first server cluster 203; during the internal transmission process, the target port of the target server needs to be converted from the public network address to the intranet address, as shown in the following Table 2:

Table II

According to the above table, after the first server cluster 203 receives the third data packet, the public network address of the third data packet is converted from IP2 to IP3, and the public network port is converted from Port-A to Port-a, Port-b, Port-c and Port-d. The audio RTP in the third data packet is sent to Port-a, the audio RTCP in the third data packet is sent to Port-b, the video RTP in the third data packet is sent to Port-c, and the video RTCP in the third data packet is sent to Port-d, and a first mapping relationship is established, that is, the public network port of IP1 is mapped to the intranet port of IP3.

Please refer to FIG. 8 , which is a structural diagram of a data transmission system provided in an embodiment of the present application. As shown in FIG. 8 , the data transmission system 800 includes a target terminal 801, a first server cluster 803, a second server cluster 802 and a target server 804. The first server cluster 803 is respectively connected to the second server cluster 802 and the target server 404 in communication, and the target terminal 801 is connected to the second server cluster 802 in communication;

The first server cluster 803 is used to receive N first data packets sent by the second server cluster 802;

The first server cluster 803 is also used to send the N first data packets to the target port in the target server 804 according to a preset first mapping relationship; the first mapping relationship is used to characterize the mapping relationship between the address information of the target terminal 801 and the address information of the target port.

The second server cluster is an SLB server, which provides a public network entrance and sends the data packet received from the client of the target terminal to the first server cluster, or sends the data packet sent by the first server cluster to the target terminal. The data packet includes the address information of the target terminal, and the types of N data packets are different, and N is a positive integer greater than 1.

It should be understood that the second server cluster receives the fourth data packet, which includes the address information of the target terminal. The second server cluster performs a hash calculation on the address information to obtain a third hash value. At the same time, the second server cluster also obtains the address information of the first server cluster, and establishes a second mapping relationship based on the address information of the target terminal and the address information of the first server cluster. After the second server cluster receives the first data packet, it performs a hash calculation on the address information of the first data packet to determine the first hash value. When the first hash value is the same as the third hash value, the second server cluster sends the first data packet to the first server cluster according to the second mapping relationship.

In the process of data transmission, in order to keep the path transmitted to the target server consistent, the second server cluster determines that a first server in the first server cluster is the first target server according to the third hash value, and then sends N first data packets to the first target server. After receiving the N first data packets, the first target server sends N first data packets to the target server. In this way, the N first data packets received by the target server are all sent by the first target server, ensuring the consistency of the path.

The hash ring is a virtual ring, and the second server cluster determines the first target server according to the hash ring.

Exemplarily, as shown in FIG3 , there are M nodes on the hash ring, and each node corresponds to a first server. Among them, the range of hash values between each node is represented. For example, there are 3 nodes on the hash ring, node R1, node R2 and node R3, the range of hash values between node R1 and node R2 is [0,100], the range of hash values between node R2 and node R3 is [100,200], and the range of hash values between node R3 and node R1 is [200,300]. The second server cluster determines the first server corresponding to the node on the hash ring based on the calculated third hash value.

Among them, after the second server cluster determines the hash value, a node on the hash ring is determined. For example, the third hash value is determined to be 150, and the hash ring position corresponding to the third hash value is between nodes R2 and R3. At this time, a selection order is specified, and the nearest node is selected in order as the node corresponding to the first server. For example, in a clockwise order, the nearest node is R3, that is, the first server corresponding to node R3 is the first target server.

Optionally, an association relationship is established between the N first servers based on a hash ring and P virtual servers, a virtual server is set between the first servers that are adjacent to each other on the hash ring, and the address information of the virtual server is the same as the address information of the corresponding first server, and P is a positive integer greater than 1;

The second server cluster 802 is further configured to generate a plurality of virtual servers in the hash ring and the P virtual servers according to the third hash value. The corresponding location information on the server determines the first target server.

It should be understood that the M first servers establish an association relationship based on the hash ring. When the second server cluster determines the first target server, there is a situation where more access is concentrated on a certain node. Therefore, a virtual server is introduced based on this to reduce the access volume of a single node.

For example, the hash value range between node R1-1 and node R2-1 is [0,33], the hash value range between node R2-1 and node R3-1 is [34,67], and the hash value range between node R3-1 and node R1-2 is [68,100]. Among them, the range between node R1-1 and node R1-2 is still [0,100], which corresponds to the range between node R1-1 and node R2-1, node R2-1 and node R3-1, and node R3-1 and node R1-2. The address information corresponding to node R1-1, node R2-1, and node R3-1 are all one address information, which is the address information of the first server R1, wherein node R1-1 and node R2-1 are virtual server nodes. When the hash ring position determined by the second server cluster is node R1-1, node R2-1, and node R3-1, the second server cluster determines that the first target server is the first server R1, as shown in Figure 5.

It should be understood that the second server cluster includes multiple second servers, and one of the multiple second servers is determined as the second target server, and the second target server is used to transmit N first data packets to the first target server. The second server cluster determines the second target server through the third hash value and the hash ring, which is the same as determining the first target server through the third hash value and the hash ring, and will not be repeated here.

Optionally, as shown in Figure 10, when the first target server is abnormal and cannot transmit data, the target terminal sends a third data packet again to redetermine the first target server. For example, when the first target server is R1, server R1 is abnormal, and the target terminal sends a third data packet again, at which time the first server cluster redetermines server R2 as the first target server based on the hash ring.

In this embodiment, the first target server is determined by the target terminal resending the third data packet, thereby achieving replacement of the first target server during the data transmission process and ensuring the continuity of data transmission.

Optionally, as shown in Figure 11, when the second target server is abnormal and cannot transmit data, the target terminal sends a third data packet again to redetermine the second target server. For example, when the second target server is L1, server L1 is abnormal, and the target terminal sends a third data packet again, at which time the second server cluster redetermines server L2 as the second target server based on the hash ring.

In this embodiment, the second target server is determined by the target terminal resending the third data packet, thereby achieving replacement of the second target server during the data transmission process and ensuring the continuity of data transmission.
